Assembled valve seal can permits full pressure connect and disconnect , without seal washout .
Corrosion resistant brass body makes this coupling compatible with a broad range of media and provides versatility .
Flat face valves are easily wiped clean during connection .
The screw system allows the connection either with male or female under pressure .
The flange is designed to give a positive ‘’no-slip’’bulkhead mounting to reduce down time .
It offers brass caps and plugs .
